Even though I expressed my slight frustration earlier, in my opinion you only need to know a couple of steps in Viennese in order for it to be fun .

One thing that may seem to contradict most perceptions, but to me, it's actually easier to do Standard Viennese in a social setting, because there are fewer steps, and you're not throwing any "curves" at the lady... just going left, right, and throwing in a few wisks/balances every now and then. With American Style, unless you know about the person's dance history, you usually can't just impose/lead whatever you want. I hope I'm not considered a trator, since I compete in American Smooth

I agree with Porfirio. VW is a dance which requires good solid technique and an excellent topline. And it is a relatively simple syllabus, so as a dancer you can focus on these things in the dance.
In Ireland, we have the "old time Waltz" which is very popular and EVERY social dancer dances it. It's similar to VW but at a slower tempo (about 55 BPM) and without the Viennese cross footwork and no flekerels.
In Ireland, only the very top dancers attempt the flekerels in VW.
I was reading a book by Harry Smith-Hampshire (a famous UK dancer who was 8 times World champ at VW - i think)). He pointed out that the flekerels were the original dance, and the travelling turns only came later. such is progress i guess.

There are very few steps in the International Viennese Waltz. The good thing about learning International is that the repetitive nature of the dance will expose flaws in your technique that you may not notice practicing American Style VW.

I think that if you are not interested in learning the closed position technique that comes with all standard dances, that you stick to American Style. This will provide you with more variation and steps to use socially.

Happy Dancing!
